I have had the same issue and it's become almost predictable. As far as I can tell the turn signals are cancelled based on some combination your throttle input, clutch, shifting, and possibly tilt sensor. The most common spots for them to auto cancel on me is when I get over into the turn lane or if a light turns green as I'm braking and I get off the clutch and roll on the throttle.
It's super annoying and dangerous, but I've learned to check the signal in those situations. I haven't gotten to the point where I want to disable the auto cancel, but I do believe there is a module that controls it which is suppose to be sensitive to the electrical load on the front turn signals, which makes me believe it can be bypassed or removed.
